Charge Efficiency around 80% - normal?

stefan.wehinger@gmail.com 1 month ago 0

My charge efficiency is around 80%.

Model S 75D Mid 2017, 11kW AC charger

Webasto Pure 11kW charging station (https://webasto-charging.com/de_at/catalog/product/view/id/17/s/webasto-ac-pure-s-22kw/category/3/)

Question: Is this low efficiency normal? The losses seems very high!

Thank you all, Stefan
